I'm having problems with blocking Google DNS on my Ultra Hub. The static routes appear to be loaded correctly:

but when I ping the IP address I get a response:

I've seen someone else having a similar problem on the Vodafone Community but there's been no response. Does anyone have any suggestions, please?

Isn't 192.168.1.1 the default Ultra Hub IP address? Just set to some other IP on that range that's not assigned. You should also set the interface to LAN so it doesn't bother to send it out the WAN connection but that's not a big deal.

Yep so what you have done is told the ultra hub the correct way to get to 8.8.8.8.
So as above, just pick a random IP address on your LAN and then the router will send requests for 8.8.8.8 to that IP address which obviously won't get anywhwre

Thanks for the quick replies. @yitz, unfortunately it doesn't have LAN, only wan, wwan, ull_voice, ull_video, vdsl_ull_voice, vdsl_ull_video and FTTH_TIVO.

I've amended both as below:

I've restarted the router and repinged but I'm still getting through to Google. What am I missing, please? Do I need to switch IPv6 off?

What about a gateway IP other than 192.168.1.255 (as that is the broadcast address) say 192.168.1.254

Or try something else altogether like 10.1.1.1

I've tried both 192.168.1.254 and 10.1.1.1:

It's still managing to find Google. Is there anything else I can try?

I'm starting to suspect that the Static Routing doesn't actually work on the Ultra Hub. Is there any test that I can do to prove that it works?

What if you set the metric to 0, and try one of the other interfaces like "FTTH_TIVO". Not sure what that is exactly but if it's an unconnected interface it could work... It seems the firmware loaded on this unit has also been customised for Vodafone in Australia.

I guess "null routing" is not what the static routing feature is intended for as in proper routers you would be able to select a "null" interface but with these devices usually specifying an invalid gateway address has the same effect. The primary purpose on home routers / residential gateways is actually to forward traffic onto a VPN e.g. PPTP. Some ISPs use customer routers they have assigned as public Wi-Fi hotspots which encapsulate traffic from the public hotspot SSID and route it back to their VPN.

Is there a page somewhere in the GUI that displays the routing table?

Reading the thread on Vodafone Community it does seem it may not actually be implemented...

http://community.vodafone.co.nz/t5/Modems-Wi-Fi/Static-route-on-Vodafone-Ultra-Hub/m-p/217589/
(..but then again if the LAN interface is not an option their set up wouldn't work anyhow...)

Here's the Routing Table:

I'll try a few permutations later. That's one of the threads that I've seen and it doesn't fill me with hope that it actually works. It also rules out the prospect of using another router as I need the Ultra Hub for the landline (dinosaur that I am).

This has also been raised and answered in VF Community

In brief: The static routing on the UltraHub is designed for a scenario with multiple WAN (uplink) connections. You can't create a route towards the LAN

You bet me to it Mike. Was going to add:

Depending on exactly what you're trying to do, you may already be 'blocking' Google DNS: with Secure DNS switched on (it is by default), then any DNS query towards Google DNS is actually diverted to the default Vodafone DNS addresses. If you'd like to verify this yourself try this (courtesy of http://netengv6.blogspot.co.nz/2013/05/dig-whoamiakamainet.html):

nslookup myip.opendns.com 208.67.222.222 => should return your own (public) IP address with Secure DNS off, and no response when on.

Thanks for the info. However, I have Secure DNS switched off as I would like to use another provider's DNS services. How can I do that with the Ultra Hub, please?

Can't think of a way to use alternative DNS while blocking Google DNS on the Ultra Hub. Might be time to look at a gateway with more features/flexibility.

Certainly seriously thinking about it. As I'm on fibre, wouldn't I still need the UH for the landline?

Does the Ultra Hub get it's DNS server's from the PPPoE or DHCP connection?

If so, is there in an option in the WAN interface to manually set a DNS server at that point?

You could then use something like Pi-Hole on your local network, tell the router to use that as the DNS server.

The enable that "Secure DNS" so your LAN sends everything to the router, which now has been "assigned" another DNS server which it thinks it got from the ISP, but it actually got from you.

That's a bit beyond me, I'm afraid. Hopefully someone else can answer.

The house does have a number of ethernet ports. Am I right in saying that I can plug a router in each one of them without conflict? If that's the case, then the answer could be to use the Ultra Hub purely for the landline and switch the wifi off and then use something else for the rest of the network.
